Title: Fibrous non-woven sheet materials and the production thereof
Inventor: MARRINAN HENRY JAMES
IPC: D04H1/435
Filed: 1963-03-04
Abstract: A fibrous fabric (see Division D1) which is prepared by a shrinkage treatment from a batt of fibres 50-100% of which shrink by at least 10% under a load of 0,005 grams per denier at 150  DEG C. is coated on one or both sides with a polyurethane resin and patterned to resemble leather or further treated to simulate suede.  The batt of fibres may include as high-shrinkage-force fibres polypropylene fibres which are at least partially drawn, together with natural fibres or polyesters, polyamides or other synthetic fibres exhibiting low shrinkage at the treatment temperature envisaged, and may further be treated with resinous or elastomeric bonding or filling agents before being coated as above.  Specifications 787,900 and 908,613 also are referred to.ALSO:A process for the production of fibrous non-woven sheet materials comprises forming and then subjecting to a shrinkage treatment a batt of fibres which contains 50 to 100% by weight of fibres which have the property of shrinking by at least 10% of their original length when under a load of 0.005 grams per denier at 150 DEG C.  The fibres preferably are not embrittled by such heat treatment.  Suitable fibres are those of polypropylene which are at least partially drawn.  The batt may be needled to provide initial consolidation, then heated, e.g. by pressurised steam, to about 150 DEG C. to cause shrinkage of the fibres and thereby to consolidate the web further.  The batt may be impregnated with a resinous or elastomeric filling compound before or after shrinkage, e.g. a butadiene-acrylonitrile copolymer may be applied to the impregnated batt which is then squeezed, dried and heated under pressure to provide a leather-like sheet. Coagulation or curing of the filling compound may be effected simultaneously with shrinking of the batt. Other fibres which may be present in the batt include natural fibres or polyesters, polyamides or other fibres which exhibit low shrinkage at the treatment temperature envisaged.  The fabric may be further coated on one or both sides, e.g. with a poly-urethane resin, patterned to resemble leather or further treated to simulate suede. Known bonding or filling agents referred to include natural latex emulsions, polyester-urethanes, polyether urethanes, copolymers of acrylonitrile with butadiene or certain acrylate esters, neoprene rubbers, rubbery polymers and co-polymers derived from butadiene or isoprene, and plasticised polyvinyl chloride.  Specifications 787,900 and 908,613 also are referred to.

Scintillation phosphor material comprises an autogenously bonded polycrystalline compact of a host compound and an activator. A mixed crystal may be crystallized from a solution of an activator in a molten mass of the host crystals, e.g., thallium chloride or iodide crystals are added to fused sodium iodide or lithium iodide. The mixture is cooled and the mixed crystals are further sub-divided by grinding and then compacted in a device as in Fig. 2 comprising a base plate 18, top plate 19 and body 17, seal rings 21, 22 of resilient material, split cones 24, 25 and a reciprocating plunger 28. A further sealing ring 30 and a helical returns spring 31 are provided round the neck of the plunger. Pressures of 120,000 lbs./sq. in. can be applied. A bore 36 connects the moulding cavity to a source of reduced pressure so as to eliminate vacuum spaces between the crystals and prevent hydrolysis. The mixed crystals may also be formed by dissolving in a solvent and evaporating ; or a solution of host and activator compounds in a mixture of acetone and dry ice is rapidly cooled, subjected to freeze drying and dried over dessicating material. Cadmium sulphide crystals containing excess cadmium, naphthalene or anthracene may be similarly compacted. In a further method, microcrystalline particles of the host and the activator are compacted and heat treated to cause solid state diffusion. Zinc sulphide with a salt of silver, copper or manganese and a flux, e.g., sodium chloride, may be treated in this manner at a temperature below the melting point of the phosphor. The content of thallium in NaI/Tl may be 0À005-1 per cent, preferably 0À1 per cent.

Title: Milking equipment
IPC: A01J7/04
Filed: 1959-02-03
Abstract: 918,766. Milking installations. DYKE. E. D. Aug. 7, 1959 [Feb. 3, 1959], No 3859/59. Class 5(1). A milking installation, particularly for use when cows are kept in their stalls for periods covering more than one milking, comprises an automatic system whereby at a pre-set time milk is extracted from the animals and conveyed to a storage tank, and between milkings the milking and conveying apparatus is washed through, first with water and then with a solution of a cleaning agent, all without the necessity of human intervention. Fig. 1 illustrates the installation as applied to a single stall, the system including a teat cup cluster TC which can be brought into communication with the vacuum pump VP via a pulsator PR and vacuum trap VT; a milk storage tank MRT, a water tank WT and a tank CST for the cleaning solution, the latter being in two parts and provided with a pump TP for pumping solution from one part to the other. The separate milking and washing operations are initiated by the adjustment of various valves incorporated in the system and by the operation of pumps VP and or TP such adjustment and operation being effected automatically by means of timing equipment TE, controlled by mechanism RC which has connections to the various components of the equipment. Firstly, by starting the pump VP, opening valves MC, IVC, IMC, and setting the valve MTC to connect the milk line ML with the storage tank MRT, milk is extracted from the animal and conveyed to the storage tank. At the end of the milking period, valves IVC and MC are closed, CLC is set to connect the water tank WT with the tube CL, MTC and OC are set to connect the milk line ML with a water outlet WL, and the valve ICC is opened. Water then leaves the tank WT by gravity and washes through the teat cup cluster as described below, and through the milk line ML. Finally, by starting the pump TP, setting the valve OC to connect the milk line to one side of the tank CST, setting CLC to connect the tube CL to the other side of the tank CST and setting the valve PRC to connect the vacuum pump to the tank CST, the cleansing solution can be made to flow around the milking apparatus in a closed circuit. After one or more washing and cleansing processes and after the required time interval, the whole operation is automatically repeated. The teat cup clusters each comprise teat cups attached to a light, flexible, udder harness which is strapped to the animal's body. The individual teat cups comprise a light-weight shell TCB closed at the top by an annular, flexible membrane FM and containing a flexible lining TCL, the space between the shell and the lining being in communication with the pulsator RT via the tube IVT, and the interior of the membrane TCL being in communication with the milk line via the tube IMT. During the washing processes, liquid enters a hollow ring LMR at the mouth of the teat cup, via the tubes CL and ICT, is sprayed on to the teat and the lining TCL through holes CH, and is drawn off from the teat cup along the tubes IMT and ML either to the water outlet WL, or to the storage tank CST.
